Abstract
BACKGROUND The endocytoscope with ultra-high magnification (x 520) allows us to observe the cellular structure of the colon epithelium during colonoscopy, known as virtual histopathology. We hypothesized that the endocytoscope could directly observe colorectal histopathological specimens and store them as endocyto-pathological images by the endoscopists without a microscope, potentially saving the burden on histopathologists.
AIM To assess the feasibility of endocyto-pathological images taken by an endoscopist as adequate materials for histopathological diagnosis.
METHODS Three gastrointestinal pathologists were invited and asked to diagnose 40 cases of endocyto-pathological images of colorectal specimens. Each case contained seven endocyto-pathological images taken by an endoscopist, consisting of one loupe image, three low-magnification images, and three ultra-high magnification images. The participants chose hyperplastic polyp or low-grade adenoma for 20 cases of endocyto-pathological images (10 hyperplastic polyps, and 10 Low-grade adenomas in conventional histopathology) in study 1 and high-grade adenoma/ shallow invasive cancer or deep invasive cancer for 20 cases [10 tumor in situ/T1a and 10 T1b] in study 2. We investigated the agreement between the histopathological diagnosis using the endocyto-pathological images and conventional histopathological diagnosis.
RESULTS Agreement between the endocyto-pathological and conventional histopathological diagnosis by the three gastrointestinal pathologists was 100% (95%CI: 94.0%–100%) in studies 1 and 2. The interobserver agreement among the three gastrointestinal pathologists was 100%, and the κ coefficient was 1.00 in both studies.
CONCLUSION Endocyto-pathological images were adequate and reliable materials for histopathological diagnosis.

Abstract
Fundic gland polyps (FGPs) are the most common gastric polyps and have been regarded as benign lesions with little malignant potential, except in the setting of familial adenomatous polyposis. However, in recent years, the prevalence of FGPs has been increasing along with the widespread and frequent use of proton pump inhibitors (PPIs). To date, several cases of FGPs with dysplasia or carcinoma (FGPD/CAs) have been reported. In this review, we evaluated the clinical and endoscopic characteristics of sporadic FGPD/CAs. Majority of the patients with sporadic FGPD/CAs were middle-aged women receiving PPI therapy and without Helicobacter pylori (H. pylori) infection. Majority of the sporadic FGPD/ CAs occurred in the body of the stomach and were sessile and small with a mean size of 5.4 mm. The sporadic FGPs with carcinoma showed redness, irregular surface structure, depression, or erosion during white light observation and irregular microvessels on the lesion surface during magnifying narrow-band imaging. In addition, sporadic FGPs, even with dysplasia, are likely to progress to cancer slowly. Therefore, frequent endoscopy is not required for patients with sporadic FGPs. However, histopathological evaluation is necessary if endoscopic findings different from ordinary FGPs are observed, regardless of their size. In the future, the prevalence of FGPs is expected to further increase along with the widespread and frequent use of PPIs and decreasing infection rate of H. pylori. Currently, it is unclear whether FGPD/CAs will also increase in the same way as FGPs. However, the trends of these lesions warrant further attention in the future.

Abstract
RATIONALE Brunner gland hamartoma (BGH) is a rare tumor of the duodenum. Although BGH is a benign tumor, larger lesion with gastrointestinal symptoms requires tumor removal. We report a giant BGH, successfully treated by endoscopic excision followed by transanal retrieval. PATIENT CONCERNS A 38-year-old woman complained of severe anemia, tarry stool, and vomiting. DIAGNOSES Esophagogastroduodenoscopy (EGD) showed a pedunculated giant submucosal mass at the duodenal bulb. INTERVENTIONS We attempted to remove it because the lesion seemed to be responsible for patient's anemia and vomiting. The lesion had clear but bulky stalk. We carefully cut the stalk using needle-knife and IT knife2. We tried to retrieve specimen, but the mass could not pass through the pyloric ring because of its size. Then we tried to obtain the specimen from anus. Polyethylene glycol solution was administered to accelerate rapid excretion. OUTCOMES The mass was successfully removed and was histologically confirmed as a giant BGH, measuring 55 mm in size. LESSONS Reports about endoscopic resection of giant BGH are rare. Moreover, our case is the first report of transanal retrieval of resected specimen using polyethylene glycol solution. Endoscopic resection of BGH is less-invasive but can be more challenging if the mass is large. Our case provides useful option for endoscopic treatment of giant BGH.

Abstract
To advance the automated inspection and maintenance of the inner wall of tunnels, an advanced inspection system aimed at regulating traffic was developed. In this inspection system, a guide frame was installed along the tunnel ceiling wall that is above the protection frame built over the road and resembles a gantry crane. The inspection device was fitted with an inspection guide frame (IGF), which stabilized its movement and improved its accuracy. However, as this protection frame moves along the tunnel, the guide frame should have the capacity to avoid convex obstacles such as the duct fan, the lamp and road traffic signs within the tunnel. Therefore, the entire inspection guide frame is made of variable geometry truss (VGT), which makes it possible to suitably alter the shape of the guide frame whenever necessary and pass it through the tunnel. To enable the guide frame adapt to any shape, the inverse analysis method and mathematical interpolation method were applied. The orientation of each frame was reversely analyzed according to the shape of the obstacle measured using the laser range finder (LRF), and the frame’s actuator was controlled simultaneously. We investigated the construction of a system that can perform a series of tasks such as searching for obstacles and positioning, frame shape simulation, frame shape change, inspection of the device and movement. By applying spline interpolation, we managed to practically determine the shape of the guide frame that would avoid obstacles.

Abstract
Users of bridges and tunnels are generally concerned about the aging of these structures. Periodic inspections are necessary to keep old bridges and tunnels healthy. Inspection engineers must approach the inspection points as close as possible by mobile elevating of the work platform for close visual inspection of lining concrete. The inspection of a road tunnel particularly requires traffic regulation. Furthermore, it takes much time to perform visual inspection and hammering test for the vast area. Moreover, the inspection results have variations by inspectors. We propose an “Inspection Vehicle” for inspection of tunnel lining concrete by a new technology for infrastructure maintenance. This study reports the finding on element technology of an inspection vehicle and applies a tunnel inspection test.

Abstract
The objective of this study was to investigate cyclical changes in endometrial thickness in relation to progesterone (P4) and estradiol-17β (E2) concentrations during natural and induced estrus in 15 cows. In the prostaglandin (PG) F2α-induced estrus group, ultrasonography (USG) at 6-h intervals was used to determine endometrial thickness 48-24 h before the PGF2α treatment until 24 h after ovulation (ovulation = Day 0). In the natural estrus group, USG was performed every 48 h from Day 3 to Days 15-18 after the first ovulation, and then every 6 h until 24 h after ovulation. Endometrial thickness was standardized using Day 13 as a reference day. Blood was collected during every USG examination and plasma P4 and E2 concentrations were determined. Endometrial thickness of the induced estrus group (n = 11) was greater than that of the natural estrus group (n = 9) between 60 and 12 h before ovulation (P < 0.05). In the natural estrus group, prior to an increase in endometrial thickness, a decrease in P4 and an increase in E2 were detected. In the induced estrus group, based on the time of ovulation, an increase in endometrial thickness was detected at the same time of a decrease in P4 before an increase in E2. These results suggest that decreases in P4 concentrations may be a cue to changes in endometrial thickness, while increases in E2 concentrations appear to sustain and/or enhance these changes.

Abstract
AIMS To elucidate varicella zoster virus (VZV)-specific cell-mediated immunity and humoral immunogenicity against live attenuated Oka varicella zoster vaccine concurrently vaccinated with 23-valent pneumococcal polysaccharide vaccine (PPSV23) in elderly people with diabetes mellitus. METHODS This double-blind randomized controlled single-centre study of 60-70-year-old people with diabetes compared immunity and safety profiles 3 months after one dose of varicella zoster vaccine or placebo. PPSV23 was immunized simultaneously. Primary analysis evaluated cell-mediated immunity using the VZV skin test. Secondary analyses were a VZV interferon-γ enzyme-linked immunospot (ELISPOT) assay and immunoadherence haemagglutination test. Adverse experiences were recorded using diary questionnaires. RESULTS By intent-to-treat analysis, 27 participants with diabetes who had been administered the vaccine were compared with 27 participants who were given a placebo. Changes in skin test scores were 0.41 ± 0.80 and 0.11 ± 0.93 (P = 0.2155), and geometric mean fold rises of the ELISPOT counts were 1.2 [95% confidence interval (CI) 0.2, 7.9] and 1.2 (95% CI 0.2, 7.3) (P = 0.989) in the vaccine and placebo groups, respectively. The geometric mean titre did not increase 3 months after vaccination in either group. No vaccination-related severe adverse experience was reported and no participant developed herpes zoster. DISCUSSION Our previous results demonstrated that varicella zoster vaccine safely enhanced VZV-specific immunity in elderly people with or without diabetes. The results of this study showed that varicella zoster vaccine can be used safely, but it cannot boost virus-specific immunity in elderly people with diabetes when administered with concurrent PPSV23. Alternative strategies are needed to prevent VZV-associated diseases in this population.

Abstract
Robot and mechatronics technologies in the construction industry, as in the manufacturing industry, are, first of all, expected to help provide high-quality structures and services safely in the shortest possible time at the lowest possible expense. Increasingly greater expectations have arisen since the 2011 Great East Japan Earthquake in regard to technologies involving disaster response and global environment protection. Under these circumstances, we are publishing a special issue on element technologies required for construction robots, and technologies adopted at actual disaster sites. These papers include one each on automatic and drive control technologies for heavy machinery, five on remote operations, three on position measurement and detection technologies, and three on technologies to be used at actual disaster sites. Application fields of these technologies are broad enough to cover all building and civil engineering work, network systems to be incorporated into structures, disaster response, marine development, and space development. Construction robots have always required robust robot technologies for severe outdoor work. We hope this special issue will help to accelerate the research and development of construction robots, to promote practical applications, and to support the utilization of element technologies in special environments in addition to outdoor environments.

Abstract
This paper describes a development of high accuracy position marking system applying the mobile robot and survey system. In the construction process of foundation works, the initial marking on the base floor is very important work to set and built the construction materials exactly. However, the marking errors were often reported by human error of survey worker. This trouble causes not only the lack of construction confidence but also the decrease of work efficiency. In order to accomplish high accuracy marking and to reduce the human errors, the automated marking system was developed using mobile robot and two survey system with laser range finder and tracking total station. In this mobile robot, the marking device was installed at robot center and the error between right target point and mark stamp point could be modified exactly. Using this marking system, high accuracy position marking on the base floor could be executed. The marking process controlled by the automatic operation, the high efficient and the high accuracy foundation work, was performed.

Abstract
This paper describes a study of high accuracy and low cost position measurement system using Laser Range Finder (LRF), and its application for construction pile work. Since the LRF is a sensor which can measure distance to surfaces of objects by radiating laser beams from itself and receiving the reflected ones, an obtained data from the LRF are nothing more than the contours of objects. In proposed system, the obtained data from LRF assumed the arc-shaped contours of the bar, the center position was analyzed introducing the least square method and maximum likelihood estimation. The error between the analysis and the measurement corresponds enough to the allowable accurate range. Additionally, improving the angular resolution of the LRF by using a pan unit, the highest accurate center position was able to be acquired. Applying this system to the construction work, the high accurate pile marking and the pile drive positioning were recognized. Since this measurement was achieved by only a worker and the position and direction of the worker was easily found, the high efficient and short term works were surely performed.

Abstract
An increased incidence of nosocomial and community-acquired infections caused by methicillin-resistant Staphylococcus aureus (MRSA) has been observed worldwide. The molecular characterization of MRSA has played an important role in demonstrating the existence of internationally disseminated clones. The use of molecular biology methods in the surveillance programs has enabled the tracking of MRSA spread within and among hospitals. These data are useful to alert nosocomial infection control programs about the potential introduction of these epidemic clones in their areas. Four MRSA blood culture isolates from patients hospitalized at two hospitals in the city of São Paulo, Brazil, were analyzed; one of them was community acquired. The isolates were characterized as SCCmec, mecA and PVL by PCR, pulsed-field gel electrophoresis (PFGE) profile and molecular sequence typing (MLST) genotyping. The isolates presented type IV SCCmec, and none proved to be positive for PVL. The isolates showed a PFGE profile similar to the pediatric clone. MLST genotyping demonstrated that the isolates belonged to clonal complex 5 (CC5), showing a new yqiL allele gene, resulting in a new sequence typing (ST) (1176). Our results showed that strains of MRSA carrying a new ST are emerging in community and nosocomial infections, including bacteremia, in São Paulo, Brazil.

Abstract
This paper describes a movable arch roof with external panels as an actual design of an adaptive structure using a VGT (Variable Geometry Truss) mechanism comprising an elementary truss structure with extendable members. This movable arch structure comprises several VGT units jointed in series and pin jointed at each end. It is a stable structure because its edge is restrained, but this reduces its variety of shape change. Various arch shapes can be determined by using inverse analysis to solve the structure shape from the member lengths. An actual movable roof pavilion composed of such a movable arch and an external panel was designed, and the behaviors of a movable roof and the joint mechanism of the roof elements were verified by numerical simulation and a model experiment. As a result, the performance of the proposed movable roof structure was confirmed, and the basic technology and design approach were established.

Abstract
BACKGROUND We previously reported that intratracheal delivery of alloantigen induced regulatory cells in a mouse heart transplantation model. We investigated the roles of costimulatory pathways in the induction of regulatory cells by intratracheal delivery of alloantigen. METHODS CBA (H-2k) mice were pretreated with intratracheal delivery of splenocytes (1 x 10(7)) from C57BL/10 (H-2b) mice and administration of monoclonal antibodies (mAb) specific for programmed death (PD)-1 and its ligands, programmed death-ligand (PD-L)1 and PD-L2, CD70, CD134 ligand (CD134L), CD153, CD137L, or receptor activator of nuclear factor-kappaB (NF-kappaB) (RANK). Seven days later, naive CBA mice underwent adoptive transfer of splenocytes (5 x 10(7)) from the pretreated CBA mice and transplantation of C57BL/10 heart. RESULTS Adoptive transfer of splenocytes from CBA mice that had been pretreated with intratracheal delivery of C57BL/10 splenocytes significantly prolonged the survival of C57BL/10 allograft (median survival time [MST], 68 days) as compared with adoptive transfer from untreated CBA mice (MST, 12 days). Concomitant administration of control immunoglobulin (Ig)G, anti-PD-L2 mAb, or anti-CD137L along with intratracheal delivery did not significantly affect the prolongation (MST, 72, 68, and 65 days, respectively). In contrast, anti-PD-1, anti-PD-L1, anti-CD70, anti-CD134L, anti-CD153, or anti-RANK mAb abrogated the prolongation induced by adoptive transfer from the pretreated mice with intratracheal delivery (MST, 18, 17, 16, 14, 10, and 18 days, respectively). CONCLUSION The PD-1/PD-L1, CD27/CD70, CD134/CD134L, CD30/CD153, and tumor necrosis factor (TNF)-related activation-induced cytokine (TRANCE)/RANK interactions are independently required for generation of regulatory cells by intratracheal delivery of alloantigen.

Abstract
INTRODUCTION A virally induced alloreactive memory seems to represent a potent barrier to tolerance induction but the combination of 15-deoxyspergualin (DSG), an inhibitor of NFkB translocation, with costimulation blockade (CB)-based chimerism as an induction regimen can overcome a preformed anti-donor memory response. In this study, we investigate the ability of DSG with CB to inhibit a naive alloimmune responses. METHODS A BALB/c (H-2d) skin or heart was transplanted into a C57BL/6 (H-2b) recipient treated with anti-CD154 mAb (MR1; 500 mcg/d on days 0, 2, 4, 6) alone, DSG (5 mg/kg/d, days 0 to 7) alone, or both agents. Proliferation of alloreactive T cells after each treatment was also examined using a graft-versus-host disease (GvHD) model using the fluorescent dye CFSE. RESULTS Treatment with DSG alone induced prolonged survival of the cardiac allografts (median survival time [MST]: 97.5 days). MR1 alone induced indefinite survival of cardiac allografts, although at 150 days after transplantation, the histology showed changes characteristic of chronic rejection, including interstitial fibrosis, infiltration of mononuclear cells, and intimal hyperplasia in coronary vessels. Combined treatment with DSG and MR1 induced donor-specific unresponsiveness in all recipients, graft histology showed only minimal infiltration. Treatment with DSG and MR1 also significantly prolonged the survival of skin allografts (MST: 31 days) compared with that of DSG or MR1 alone (MST: 17 and 14 days, respectively). In the GvHD model assessed with CFSE, the combined treatment was the more effective to suppress proliferation of alloreactive T cells while DSG alone inhibited proliferation more than MR1 alone. CONCLUSION DSG potentiates anti-CD154 therapy to suppress the alloimmune response.

Abstract
A feeder-independent cloned trophoblast cell line, HTS-1, was established from a mature placenta of Shiba goat (Capra hircus). During the growth phase, single HTS-1 cells exhibited ruffled membranes or lamellipodia often accompanied by elongated cell shape, indicating highly motile nature of the cells. At or near confluence, HTS-1 cells formed monolayers with few sign of cellular overlapping. Binucleate cells were found at a high frequency especially in the peripheral regions of monolayers. In small colonies and the monolayers, majority of HTS-1 cells assumed polygonally shaped cobble-stone like morphology characteristic to epithelial cells, although considerable variations in cellular morphology were observed despite of repeated cloning. Time-lapse video recordings of HTS-1 cells during culture revealed that not only the small colonies but also the monolayers near or at confluence were remarkably motile, often causing extreme elongation of the cells within them. The extremely plastic nature of HTS-1 cells in vitro is likely to be the reflection of the extraordinary capacity of caprine trophoblast cells to be stretched to extreme thinness in vivo as shown by electron microscopy. HTS-1 cells cultured on matrigel are highly invasive, and express MT1-MMP which, in the mouse, has been known to be expressed at the invasive edge of trophoblast both in vitro and in vivo. HTS-1 cells express placental lactogen (PL) and interferon-tau (IFNtau), as confirmed by immunocytochemistry, Western blotting and RT-PCR analysis. Both PL and IFNtau expression in the cells appeared to be down-regulated by cell-cell contact. In the medium conditioned by HTS-1 cells, the presence of secretory form of PL and IFNtau was confirmed by Western blotting. The HTS-1 cell line will serve as a useful in vitro model for the analysis of the molecular and/or cellular mechanisms underlying synepitheliochorial placentation in bovidae animals.

Abstract
It remains unclear whether lymphoma of the mucosa-associated lymphoid tissue (MALT) in the extragastric organs is related to Helicobacter pylori infection or not. This report describes three patients with rectal MALT lymphoma negative for H. pylori infection, all of whom showed disease regression after being treated with antibiotics. One patient had MALT lymphoma in both the descending colon and the rectum; the other two patients had rectal disease only. None of the patients had chronic gastritis which was detectable either endoscopically or histologically and H. pylori infection was completely ruled out by various methods, including a urease breath test. These patients received antibiotic therapy. In all the patients, regression of MALT lymphoma was observed endoscopically and histologically, and polymerase chain reaction revealed that a previously observed rearranged band of immunoglobulin heavy chain had also disappeared after antibiotic treatment. These cases therefore suggest involvement of micro-organisms other than H. pylori in the development of rectal MALT lymphoma.

Abstract
The annual multicenter studies on isolated bacteria from infections in general surgery and their antimicrobial susceptibility have been conducted in Japan since July 1982. This paper describes the results obtained in fiscal 1998 (from April 1998 to March 1999). The number of cases investigated as objectives was 225 for one year. A total of 429 strains (121 strains from primary infections and 308 strains from postoperative infections) were isolated from 183 cases (81.3% of total cases). In primary infections, the isolation rates of anaerobes and Escherichia coli were higher than in postoperative infections, while in postoperative infections, those of Gram-positive aerobes and Pseudomonas aeruginosa were higher than in primary infections. On the whole, among Gram-positive aerobes, the isolation rate of Enterococcus faecalis was the highest, followed by Staphylococcus aureus with high frequency in isolation from postoperative infections. Among Gram-positive anaerobes, Peptostreptococcus spp. and Streptococcus spp. were predominantly isolated. Among Gram-negative aerobes, E. coli, P. aeruginosa, Klebsiella pneumoniae and Enterobacter cloacae were frequently isolated. Among Gram-negative anaerobes, Bacteroides fragilis group was the majority of isolates. In primary infections, the percentage of Gram-negative aerobes has gradually increased since fiscal 1995 or 1996 with these years as the turning point, while those of Gram-positive and Gram-negative anaerobes have gradually declined. In postoperative infections, the percentage of Gram-negative anaerobes has increased continuously since the mid-1980s. The percentage of MRSA among S. aureus rose to 89.7%, which was the highest level since the beginning of this study. The susceptibilities of B. fragilis, which did not show apparent changes, were recognized to have decreased against cephems in fiscal 1998. Among other bacteria in B. fragilis group, development of resistance to cephems has continued on a long-term basis since the mid-1980s. E. coli and K. pneuminiae have obviously not changed in susceptibilities, however, the susceptibilities of isolated strains in fiscal 1998 against high-generation cephems, oxacephems and monobactams have declined. We found neither vancomycin-resistant nor teicoplanin-resistant strains of S. aureus and Enterococcus spp.

Abstract
We treated a patient with intra-peritoneal recurrent tumor from colon cancer who responded completely to chemotherapy of combined low-dose Leucovorin (LV) and 5-fluorouracil (5-FU). The patient was a 75-year-old man. He underwent resection of the transverse colon, sigmoid colon and distal stomach for colon and gastric cancers. Nine months after the operation, his CEA level increased to 39.5 ng/ml and a CT scan revealed an intra-peritoneal tumor measuring about 5 cm. He received chemotherapy of 30 mg/day of LV that was injected in a bolus and 500 mg/day of 5-FU that was given i.v. by continuous infusion for 10 days. At the end of 2 cycles of this regimen, CT scan demonstrated complete tumor remission and the patient's CEA level decreased to normal level. After an additional cycle of this regimen, he received modulated chemotherapy combined with l-Leucovorin and 5-FU as an outpatient. However, after 3 months of treatment, a recurrent tumor was detected in the same portion and the first regimen was re-started for 5 days. After 4 cycles of treatment the tumor disappeared completely from a CT scan. It is important to investigate effective regimens that do not reduce the quality of life of the patient. This clinical experience suggests that a low-dose LV/5-FU therapy may be beneficial to patients with recurrent colon cancer. Further investigation is necessary to establish an effective regimen that can be given for a long period without adverse effects on quality of life.

Abstract
OBJECTIVES This study investigated retardation of abnormal uptake of iodine-123-beta-methyl-p-iodophenyl-pentadecanoic acid(BMIPP) scintigraphy in patients with vasospastic angina. METHODS Twenty-three patients with vasospastic angina showed abnormal uptake of BMIPP before medical treatment and had coronary vasospasm induced by acetylcholine. The patients were divided into two groups according to uptake of BMIPP after medical treatment: retardation of abnormal uptake of BMIPP(Group R, n = 4) and normal uptake of BMIPP(Group N, n = 19). Frequency of chest pain, medical treatment and autonomic nervous activity were compared between the two groups. Furthermore, the frequency of chest pain and uptake of BMIPP in group R were obtained after intensive medical treatment. Autonomic nervous activity was evaluated by heart rate variability on Holter electrocardiography. Heart rate variability contained high-frequency elements(HF; 0.15-0.4 Hz) and low-frequency elements(LF; 0.04-0.15 Hz). LF/HF was estimated for sympathetic nervous activity and HF was estimated for parasympathetic nervous activity. Daytime and nighttime autonomic nervous activity were compared between the two groups. RESULTS The frequency of chest pain was higher in Group R than in Group N(p < 0.05). Medical treatment was not different between the two groups. Circadian variation of sympathetic and parasympathetic nervous activity were absent in Group R. During the nighttime, Group R showed higher sympathetic nervous activity(p < 0.05) and lower parasympathetic nervous activity(p < 0.01) than Group N. The frequency of chest pain was significantly lower after intensive medical treatment(p < 0.05), and uptake of BMIPP returned to normal in Group R. We suspected that the disorder in autonomic nervous activity was more severe in Group R, and thus induced coronary vasospasm. CONCLUSIONS Retardation of abnormal uptake of BMIPP in patients with vasospastic angina indicates poor control of coronary vasospasm. Uptake of BMIPP is useful in the evaluation of coronary vasospasm control in such patients.

Abstract
The annual multicenter studies on isolated bacteria from infections in general surgery and their antimicrobial susceptibility have been conducted in 19 facilities in Japan since July 1982. This paper describes the results obtained during the period from April 1997 to March 1998. The number of cases investigated as objectives was 215 for one year. A total of 420 strains (170 strains from primary infections and 250 strains from postoperative infections) were isolated from 174 cases (80.9% of total cases). In primary infections, the isolation rate of anaerobic bacteria was higher than in postoperative infections, while in postoperative infections, those of aerobic Gram-positive bacteria and Pseudomonas aeruginosa were higher than in primary infections. Among aerobic Gram-positive bacteria, the isolation rate of Enterococcus faecalis was the highest, followed by Staphylococcus aureus, which was frequently isolated from postoperative infections. Among anaerobic Gram-positive bacteria, Peptostreptococcus spp. and Streptococcus spp. were commonly isolated from both types of infections. Among aerobic Gram-negative bacteria, Escherichia coli was most predominantly isolated from primary infections, followed by P. aeruginosa, Klebsiella pneumoniae in this order, and from postoperative infections, P. aeruginosa was most predominantly isolated, followed by E. coli and K. pneumoniae. Among anaerobic Gram-negative bacteria, Bacteroides fragilis group was the majority of isolates from both types of infections. We found neither vancomycin nor arbekacin resistant strains of S. aureus, and found no vancomycin resistant strains of Enterococcus spp. The susceptibility of P. aeruginosa against carbapenems did not decline in the year 1997, while resistance of B. fragilis group against cephems advanced increasingly.

Abstract
Glucocorticoids are known to promote apoptosis of eosinophils, normal and neoplastic lymphoid cells, and blastic cells in some patients with acute myeloid leukemia. We investigated the biochemical signal transduction pathways, in particular, the generation of reactive oxygen species (ROS) and activation of caspases in dexamethasone (DEX)-induced apoptosis of eosinophils, and we compared them with those in DEX-sensitive myeloid and lymphoid leukemia cell lines. The GC-receptor antagonist completely abolished DEX-induced apoptosis of eosinophils and leukemia cells. Among inhibitors related to the ROS system, diphenylene iodonium (DPI), a nicotinamide adenine dinucleotide diphosphate (NADPH) oxidase inhibitor, strongly inhibited both spontaneous and DEX-induced apoptosis of eosinophils at concentrations as low as 0.2 to 2 mumol/L, while promoting apoptosis of leukemia cells in a dose-dependent manner. Apocynin, another NADPH oxidase inhibitor, and antioxidants did not affect the apoptosis of eosinophils or leukemia cells. DEX treatment did not change intracellular production of O2- and H2O2, and it decreased the extracellular release of O2- in both cells. These results suggest little or no involvement of ROS generation in DEX-induced apoptosis of both cells. Although among peptide-based caspase inhibitors, only z-VAD-FMK, a broad caspase inhibitor, partially inhibited the apoptosis of eosinophils and leukemia cells, DEX treatment increased the activities of caspases 2-, 3-, 6-, and 8-like proteases assessed by colorimetry in both cells, suggesting the involvement of a similar caspase activation pathway in DEX-induced apoptosis in both cells. DPI markedly reduced caspase 3-like activity in eosinophils, while augmenting the activity in leukemia cells, indicating that DPI acts upstream of caspase 3 activation opposingly in both cells. Thus, the action of DPI in eosinophils seems peculiar in respect to apoptosis induction, and DPI appears to exert an influence on unknown targets rather than those involved in NADPH oxidase inhibition.

Abstract
To investigate whether the difference in cellular sensitivity of Chinese hamster V79 and their H(2)O(2)-resistant variant cells (Hpr-4) to H(2)O(2) relates to the difference in intracellular Ca(2+) concentration in these cells, we measured Ca(2+) concentration by calcium ion analysis after loading these cells with Fura-2/AM. Intracellular Ca(2+) concentration increased in both Chinese hamster V79 and Hpr-4 cells as extracellular Ca(2+) concentration increased. However, the increase in intracellular Ca(2+) concentration in response to extracellular H(2)O(2) was more pronounced in Hpr-4 than V79 cells. H(2)O(2) cytotoxicity of Hpr-4 but not V79 cells was also decreased in response to the increase in extracellular Ca(2+) concentration. In parallel with the decrease in cytotoxicity in response to increasing extracellular Ca(2+) concentration, the frequency of mitochondrial DNA single strand breaks (SSB) in Hpr-4 cells also decreased without producing observable nuclear DNA SSB. Use of permeabilized V79 and Hpr-4 cells exposed to H(2)O(2) showed that mitochondrial DNA SSB decreased when extramitochondrial Ca(2+) concentration increased. These findings indicate that elevated intracellular Ca(2+) concentration may protect against H(2)O(2)-induced mitochondrial damage and cytotoxicity in these cells.

Abstract
To reduce load rotation and danger, we developed a suspender device activated by gyroscopic moment and applied it to construction work, finding that transport time of a hanging load was reduced and more comfortable and work without load rotation safer compared to conventional methods. Since characteristics of loads and restriction of work conditions vary at construction sites, the suspender device was not always suitable. To apply the device optimally, we improved the original device with new functions and the ability to handle larger loads. We describe new functions and applications and explain the device's effectiveness and efficiency.

Abstract
We used the CAG regimen (low-dose cytarabine [10 mg/m2 per 12 hours, days 1-14], aclarubicin [14 mg/m2 per day, days 1-4], and granulocyte colony-stimulating factor [200 micrograms/m2 per day, days 1-14]) for the treatment of patients with primary resistant acute myelogenous leukemia (AML) and previously untreated elderly patients with AML, secondary AML, and refractory anemia with excess blasts in transformation (RAEB-T) in addition to relapsed AML. Forty-three of 69 (62%) patients achieved complete remission (CR), including 29 of 35 (83%) patients with relapsed AML, 1 of 8 patients with primary resistant AML, 5 of 8 elderly patients with previously untreated AML, and 8 of 18 patients with previously untreated secondary AML or RAEB-T. Ten of 22 (45%) patients > or = 65 years old achieved CR. The patients who achieved CR received at least 1 course of modified CAG therapy as the first consolidation therapy, followed by various second consolidation and intensification therapies. The median disease-free survival and overall survival were 8 and 15 months, respectively, for relapsed AML; 11 and 8 months for the elderly patients; and 8 and 17 months for secondary AML and RAEB-T. Myelosuppression was mild to moderate, and other than fever, severe nonhematologic toxicity was rare. CAG as the induction therapy seems promising for the treatment of various categories of poor-prognosis AML.

Abstract
A mass in the tail of the pancreas was detected in a 62-year-old male patient who had hypergammaglobulinaemia, and was positive for antinuclear antigen and anti-SS-A antibody. Endoscopic retrograde pancreatography revealed focal irregular narrowing of the main pancreatic duct in the tail of the pancreas. Dynamic computed tomography showed swelling of the pancreatic tail, which was enhanced on delayed phase. Autoimmune pancreatitis was suspected and corticosteroid therapy was commenced. This led to significant resolution of the pancreatic stricture. It is important to recognize this clinical entity as corticosteroid therapy may avoid unnecessary surgery.

Abstract
The aim of this paper is to explore and present a proposal for a new work system for the aged worker. The method of research used to establish the system was to observe, record, and measure the actions of sitting workers performing assembly operations on electrical products. An evaluation index used in this study was obtained by measuring the motion time, cycle time per product, and the workload (CFF: Critical Flicker Fusion Frequency and Subjective Symptom of Fatigue). The results lead to the new work system being identified and to the reduction of handling motion of get and place work and the work load. It was determined that the system is adaptable for aged workers.

Abstract
We investigated the usefulness of the intracoronary administration of nicorandil (NIC) compared with that of papaverine (PAP) in the evaluation of coronary flow reserve (CFR) in 17 patients, including 10 patients with old myocardial infarction and 7 patients with angina pectoris. CFR was measured with a Doppler guidewire inserted into the distal site of the left anterior descending coronary artery during intracoronary administration of 10 mg PAP, and of 0.5 mg, 1.0 mg, 2.0 mg, and 3.0 mg NIC. We examined the changes in heart rate (HR), mean blood pressure (mBP), the total score of QTc interval on a 12-lead electrocardiogram (sigma QTc), and ST-T segment, before and after drug administration. CFR was significantly lower during administration of 0.5 mg (1.9 +/- 0.9) and 1.0 mg (2.2 +/- 0.9) NIC than during administration of PAP (2.6 +/- 1.1) (P < 0.01). There was no significant difference in the CFR during administration of 2.0 mg (2.6 +/- 1.0) or 3.0 mg (2.5 +/- 1.0) NIC and that observed during administration of PAP. The CFR during administration of PAP was significantly correlated with that during administration of 2.0 mg NIC (r2 = 0.72, P < 0.0001) and 3.0 mg NIC (r2 = 0.70, P < 0.0001). PAP, but not NIC, significantly altered the HR, mBP, and sigma QTc. Inverted T waves were observed in 14 patients, and elevation of the ST segment was observed in 4 patients during administration of PAP (including 1 patient with ventricular tachycardia). The administration of 0.5 mg to 2.0 mg NIC was not associated with ST-T segment changes, except in 1 patient, but inverted T waves were observed in 2 patients and depression of the ST segment was observed in 2 patients during administration of 3.0 mg NIC. Intracoronary administration of NIC is useful and safe for evaluating the CFR. The appropriate dose for measuring CFR is 2.0 mg nicorandil.

Abstract
To investigate the effect of pivalate on carnitine import and carnitine synthesis in the liver, we measured carnitine uptake in isolated rat hepatocytes with L-[(14)C] carnitine and concentrations of free carnitine, gamma-butyrobetaine and acylcarnitines using tandem mass spectrometry. Hepatocytes from rats treated with 20 mmol/L of pivalate for 4 wk had greater L-[(14)C] carnitine uptake than those of unsupplemented rats after 5, 10, 30 and 90 min. Addition of 1 mmol/L of pivalate or 1 mmol/L of pivaloylcarnitine to control cell suspensions did not affect L-[(14)C] carnitine uptake. The K(m) values for L-[(14)C] carnitine uptake for pivalate-treated rats were significantly lower than control (2.9 +/- 0.7 mmol/L for pivalate-treated rats, 6.2 +/- 1.1 mmol/L for controls). The concentration of free carnitine was not reduced in the liver of pivalate-treated rats, whereas the concentrations of acetylcarnitine and gamma-butyrobetaine were significantly lower than controls. In the heart and muscle the concentration of free carnitine was significantly lower and that of gamma-butyrobetaine was higher than controls. These results suggest that carnitine transport from plasma into the liver and synthesis in the liver are accelerated in rats with secondary carnitine deficiency induced by the administration of pivalate.

Abstract
Methods using tandem mass spectrometry for measurement of epsilon-trimethyllysine and gamma-butyrobetaine in human serum are described. Precursor ion scan analysis of a methylated sample was applied for gamma-butyrobetaine measurement. However, for epsilon-trimethyllysine measurement, homoarginine interfered with the methylated sample during precursor ion scan analysis. To overcome this interference, the sample was propylated and acetylated prior to precursor ion scan analysis. The obtained values resembled those obtained by enzymatic or HPLC measurement. Using tandem mass spectrometry, all members of the carnitine family, free carnitine, acylcarnitines, gamma-butyrobetaine, epsilon-trimethyllysine can be analyzed in 0.1 ml of serum. Thus, the proposed method appears to be suitable for clinical application, especially in the pediatric field.

Abstract
The effects of sports activity on carnitine metabolism were studied using mass spectrometry. Serum levels of free carnitine, acylcarnitines (acetylcarnitine, propionylcarnitine, C4-, C5- and C8-acylcarnitine) and gamma-butyrobetaine, a carnitine precursor, were determined by tandem mass spectrometry in liquid secondary ion mass ionization mode. The coefficients of variation at three different concentrations were 2.8-7.9% for gamma-butyrobetaine, and 1.2 to approximately 6.7% for free carnitine. The recoveries added to serum were 109.1% for gamma-butyrobetaine, 89.3% for free carnitine. Sports activity caused increased serum levels of gamma-butyrobetaine, acetylcarnitine, C4- and C8-acylcarnitines and decreased serum levels of free carnitine. This method requires a small amount of sample volume (20 microl of serum) and short total instrumental time for the analysis (1 h for preparation, 2 min per sample for mass spectrometric analysis). Therefore, this method can be applied to study carnitine metabolism under various conditions that affect fatty acid oxidation.

Abstract
We report two adult Japanese sisters with L-2-hydroxy-glutaric aciduria (acidemia), both of whom were much older (aged 57, 47 years old) than previously reported patients (from neonate to 44 years old), and who presented with differing severity. Magnetic resonance imaging revealed typical subcortical white matter lesions in both cases and showed brainstem atrophy and thickness of the calvarium in the elder sister. L-2-Hydroxyglutaric acid levels were increased in urine, plasma, and cerebrospinal fluid. These cases suggest that organic acid analysis is necessary even in elderly patients who seem to have neurodegenerative disorders.

Abstract
The annual multicenter studies on isolated bacteria from infections in general surgery and their antimicrobial susceptibility have been conducted in 20 facilities in Japan since July 1982. This paper describes the results obtained during period from July 1996 to June 1997. The number of cases investigated as objectives was 217 for one year. A total of 406 strains were isolated from 177 cases (81.6% of total cases). From primary infections 162 strains were isolated, and from postoperative infections 244 strains were isolated, respectively. From primary infections, anaerobic bacteria were predominant, while from postoperative infections, aerobic Gram-positive bacteria were predominant. Among aerobic Gram-positive bacteria, the isolation rate of Enterococcus spp. was the highest. In postoperative infections, the majority of them were Enterococcus faecalis, while in primary infections, many of them were Enterococcus avium. The isolation rate of Staphylococcus spp., especially from postoperative infections, followed that of Enterococcus spp. Among anaerobic Gram-positive bacteria, Peptostreptococcus spp. and Streptococcus spp. were commonly isolated from both types of infections. Among aerobic Gram-negative bacteria, Escherichia coli was the most predominantly isolated from primary infections, followed by Klebsiella pneumoniae and Pseudomonas aeruginosa in this order, and from postoperative infections, P. aeruginosa was the most predominantly isolated, followed by E. coli and Enterobacter cloacae. Among anaerobic Gram-negative bacteria, Bacteroides fragilis group was the majority of isolates from both types of infections. The isolation rate of aerobic Gram-negative bacillus has decreased with time, while those of anaerobes like B. fragilis group and of aerobic Gram-positive bacteria have gradually increased in both types of infections. We found vancomycin-resistant strains of neither Staphylacoccus aureus nor Enterococcus spp.; however, the MIC of arbekacin for one of strains of S. aureus was 100 micrograms/ml. Both the MIC90's of meropenem and imipenem/cilastatin against P. aeruginosa isolated in this term were 25 micrograms/ml, which were higher than those against the strains isolated in the previous years. Compared with the isolated strains in the year 1995, progress of resistance against carbapenem antibiotics was confirmed.

Abstract
BACKGROUND Therapeutic modalities in acute metabolic decompensation in maple syrup urine disease (MSUD) are variable, and outcomes of each therapeutic measure have been known only individually. Factors that affect neurological outcome are not clear. METHODS A questionnaire was sent throughout Japan to each pediatrician treating any of the 42 MSUD patients. RESULTS Necessary information was available for 13 patients through the questionnaire, and through a publication for one patient. In nine of the 14 patients episodes of metabolic decompensation developed in the neonatal period. In the other five, the onset of disease was delayed until infancy or later. In the nine patients with neonatal onset, a pretreatment level of plasma leucine greater than 40 mg/100 mL or a duration of altered level of alertness longer than 10 days was associated with a poor neurological outcome. The therapeutic measures employed included intravenous infusion of glucose and electrolyte solution or hypertonic glucose and electrolyte solution, exchange transfusion, peritoneal dialysis, a large dose of thiamine and intravenous hyperalimentation. All patients had survived the episodes and were alive at the time of the survey. Five of the nine patients with neonatal onset have developed neurological sequelae to varying degrees. Episodes of metabolic decompensation in infancy or thereafter did not affect, or only minimally affected, the neurological outcome. CONCLUSION Therapeutic goals to improve neurological outcome are to shorten the duration of the altered level of consciousness, and to minimize the peak plasma leucine level as much as possible.
